pdftops locale problem

[Christoph Litauer]

Hi,

I have a question concerning cups 1.1.23 running on SuSE Linux 
Enterprise Server 10 SP1.

When printing from NeoOffice (OpenOffice for Mac) to any printer on my 
printserver I just get errors like:
ERROR: undefined
OFFENDING COMMAND: 56,88

I tracked this down to the following issue: NeoOffice generates pdf code 
with font definitions containing floating point numbers (e.g. 
http://www.uni-koblenz.de/~litauer/cups/1.pdf). This file is filtered by 
pdftops which - depending on some locale settings - converts the dot 
inside of floats to a comma (e.g. 56.88 => 56,88).
I can reproduce this error via:

$ cat 1.pdf | (env PPD=/etc/cups/ppd/pdfmail.ppd LANG=de_DE 
/usr/lib/cups/filter/pdftops 11111 someuser sometitle 1 "") | grep 56,
DEBUG: pdftops - copying to temp print file 
"/var/spool/cups/tmp/484e68d911d31"
DEBUG: pdftops - opened PPD file "/etc/cups/ppd/pdfmail.ppd"...
DEBUG: pdftops - level = 2, width = 595, length = 842
[1 0 0 1 56,88 774,56] cm

The conversion doesn't take place if I ommit the PPD environment 
variable or define another locale (LANG) - unfortunately I cannot 
control this behaviour on the clients. This leads to the following 
questions:
1.) Why are the floating numbers only converted it environment variable 
PPD is set?
2.) What can I do against this conversion?

Any help is greatly appreciated, thanks in advance!

Christoph
